PLUMBING SYSTEM Filed June 2, 1928 INVEVNTOR wmuwaw Patented Nov. 3,1931 UNITED STATES PATENT OFFICE v WILLIAM C. GROENIGER, OF COLUMBUS,OHIO, ASSIGNOR OF ONE-HALF TO JOHN C.

' OROMWELL, OF ALLIANCE, OHIO PLUMBING sxs'rmr Application filed June 2,1928. Serial No. 282,342.

'5 example as closet bowls for flushing purposes.

In the'copending applications of Groeniger and Cromwell, filed June 2,1928, Serial Numbers 282,343 and 282,344, there are disclosed andclaimed certain improvements in plumbm ing system and control valvetherefor effecter referred to, adapted to comprise a portiontive forpreventing aback flow of water from the waste receptacle to the watersupply line.

The present invention relates to certain improvements in a system of thegeneral characof a flushometer control valve, a fitting for insertion inthe outlet connection from such valve, or a modifiedform of wastereceptacle with which such connection communicates, the presentinvention contemplating the provision of an airadmission opening oropenings in combination with water deflecting means cooperatingtherewith whereby the accidental escape of water through such opening oropenings is prevented.

In the accompanying drawing, there is shown by way of illustration only,an embodiment of the present invention, it being understood that thedrawing does not define the limits of my invention as changes in theconstruction and relationship of the parts disclosed therein may be madewithout departing either from the spirit of the present invention or thescope of my broader claims.

In the drawing: The figure is a vertical sectional view through aportion of a plumbing system including a flushometer valve with itsinlet and outlet connections and a portion of a was te receptacle withwhich the outlet connection communicates.

Referring more particularly to theform of the invention illustrated inthe figure, the water supply 2 is shown communicating with the inlet 3of a fiushometer valve casing 4 having an outlet connection 5. The flowbetween the inlet and outlet is controlled in known manner by the valveassembly 6 adapted to be manually operated at will by the operatinghandle 7.

deflecting means 13 extending downwardly within the projection and inspaced relation thereto to provide an annular channel 14. The projection12 may be provided with an opening or openings 15 adapted to establish aconstantly open connection between the channel 14 and the atmospherewhereby at all times air is admitted into the system at a point on theoutlet side of the valve in such manner as to preclude the possibilityof a condition of vacuum within the connection 9 such as would beeffective in siphoning any of the contents from the receptacle 10upwardly therefrom through the valve and into the water supply system.

With the form of the invention illustrated in the figure, irrespectiveof the pressure under which water is discharged through the connection1, the deflecting means 13 is op erative to prevent the back-flow ofsuch water or the splashing thereof outwardly through the openings 15.It is essential, however, that the deflecting means 13 terminate at apoint above the overflow line 16 of the waste receptacle as indicated indotted lines in the drawing.

. It will be understood by those skilled in the art that the form of theinvention illustrated herein is particularly adapted for use insubstantially vertically extending connections wherein the water flow isdownwardly and the velocity is such that a backing up of the water doesnot occur.

With the form of the invention illustrated, there is provided a systemhaving a constantly open air admission opening intermediate the valveand Waste receptacle in combination with deflecting means operative toprevent the splashing of water from the system during the flushingoperation. This constitutes one of the advantages of the presentinvention.

I claim:

1. A sanitary water flushing receptacle having a rim and an upstandingextension extending above the level of the rim by means of whichflushing water is distributed to the interior of the receptacle from asource of supply, said extension having an interior integral waterdirecting nozzle depending from the top thereof in concentric spacedrelation to the inner wall of the extension to a plane above theoverflow level of the rim, and a constantly open air port in the wall ofthe extension near the top and adjacent the side of the nozzle forobviating the possibility of the siphoning of the receptacle Water backinto the source of supply.

2. A sanitary water flushing receptacle having a rim and an integralupstanding extension extending above the level of the rim by means ofwhich flushing water is distributed to the interior of the receptaclefrom a source of supply, said extension having an interior integralwater directing nozzle depending from the top thereof in concentricspaced relation to the inner wall of the ex tension to a plane above theoverflow level of the rim, and a constantly open air port in the wall ofthe extension near the top and adjacent the side of the nozzle forobviating the possibility of the siphoning of the receptacle water backinto the source of supply.

In testimony whereof I have hereunto set my hand.

WILLIAMC. GROENIGER.
